I got the new (NIB) TP2 on Thursday. I had night class, so I had to wait until I got home to try charging it. I installed nueBattery2 right away so that I could see the charge rate, which looked OK with the new phone and battery.
Overall, I'm very happy. The guy at Sprint gave me the AC Adapter & USB cable from the box, so now I have a spare
Thanks for the feedback folks!
